(IIHIII'JIVIAN F DETROIT, MICHIGAN, ASSIGNOR T0 GENERAL BRASS COMPANY. OF DETROIT MICHIGAN, A CORPORATION OF MICHIGAN ens coox Application filed August 18, 1927. Serial No. 213,755.

The present invention pertains to a novel valve construction particularly suitable for gas cocks.

The object of the invention is to provide a i gas cook especially designed for mounting a manner that they, as 'well as the pipe -6, may

in a horizontal position and for connection to a gas supply pipe above the same. This particular arrangement of the gas cock and supply pipe lends itself to concealmentv by a.

o shield or hood extendingvfrom the cover of a gas stove, whereby the appearance of the assembly, is greatly improved.

In stoves embodying a horizontally positioned gas cook, it has been customary to al- 15 low the mixing. chamber to hang .on a proj ecting part of the rotatable plug of the cock. This form of support is unsatisfactory for the reason that-the'mixing chamber rests on a moving member and intime c'utsa groove :0 therein.

This difliculty is overcome in the present invention by providing the gas c'ock body with an outward'axial nipple which consti .tutes the outlet. The usual regulator is.

2? screwed on the outlet nipple and the mixing chamber is allowed to rest on the nipple which is a fixed part of the construction. The valve plug which rotates within the body controls the flow of gas but does not cause '20 any movement of the supporting nipple or regulator. 4

The invention 'is fully disclosed by way of example in the following description and in the accompanying drawings, in which 7 5 Figure 1 is a vertical section partly in elevation of a gas stove, showing a .gas cook mounted according to the invention;

, Fig. 2 is an elevation of the gas cock;

,Fig. 3 is a vlongitudinal vsection thereof,

' Fig. 4 is a transverse section on the line 44 of Fig. 3;

Reference to these views will now be made 'byuse of like characters which are employed to designate corresponding partsthroughout.

'In Figgre 1 is illustrated a portion of a gas stove body designated by the numeral 1 and provided with a spaced top 2. Between the body 1 and the top 2 is mounted a burner '9 3 from which extends a fuel supply pipe 4;

over the forward edge of the body where it is provided with a mixing chamber 5. The m1- meral 6 denotes the gas supply pipe running across the front of the stove.

It is'desired to mount the gas cocks in such be enclosed by a shield 7 fastened as at 8 to the forward edge of the top 2. For this purpose the gas cocks are preferably disposed horizontally, and the body of one of these cocks is illustrated as a somewhat cylindrical member 9 having a lateral or radial inlet nipple 10 threaded into the lower part of the supply pipe 6. In the body is mounted a rotatable plug 11 having an axial stem 12 equipped witha handle 13 disposed outside of the shield 7. .A cap 14 is threaded on the for- .rward end of the body, and the portion of the stem '12'disposed within the cap is surrounded by a spring 15 hearing against the cap and the forward end of the plug to hold the latter in a properly seated position. The valve plug has'an axial port 16 which may communicate with the inlet nipple 10 through a lateral or radial branch 17.

From the inner end of the valve body is extended a threaded nipple 18 in axial alinement and communication with the port 16 and serving as the outlet from the valve body. This nipple ends n a point 19 through which is formeda lateral outlet opening 20, and an apertured regulator 21 of usual construction is threaded over its end.

The end of the body inside the cap 14 is preferably notched" at '22 to receive a stop lug 23 projecting radially from theforward end of the plu'g'llu The lug is limited in its movement by the walls of the notch 22. This 'constitutesstops' for determining the closed and open positions of the cock.

' The position of the gas cock assembly is such that the mixing chamber 5 hangs on the nipple 21'. The nipple being an immovable part of the assembly, furnishes a fixed support for the mixing chamber as distinguished from present constructions of this character wherein the mixing chamber hangs or a movable part of the gas cock assembly as set forth above,

Although a specific embodiment of the invvention has been illustrated and described, it

will be understood that various alterations in the details of construction may be made within the scope of the invention as indicated by the appended claim.

What I claim is:

In a gas stove including a burner and a top member over the burner, a gas supply pipe beneath the plane of said top member, a horizontally disposed gas cock connected to said pipe, said cock including a body, a valve plug rotatably mounted therein, an outlet nipple extending'axially from said body, a fuel supply pipe communicating with said nipple and connected to said burner, a shield secured to said top member and lying partly in the plane thereof, said shield being bent to enclose said gas supply pipe and cook, and an operating handle disposed exteriorly of said shield and connected to said valve plug.

In testimony whereof I aifixmy signature.
